 # Length of a Curve
+## Review of the Mean Value Theorem
+If $f$ is a continuous function on the interval $[a, b]$ and differentiable on $(a, b)$, then there exists a number $c$ in the interval $(a, b)$ such that:
+
+$$ f'(c) = \dfrac{f(b) - f(a)}{b - a} $$
+
+This also implies that for some $c$ in the interval $(a, b)$:
+$$ f(b) - f(a) = f'(c)(b-a) $$
+
+## Intuitive Approach
+Given that we divide a curve into $n$ sub-intervals, and we can find the location of the right endpoint of each interval.
+
+With a series of points on a curve we can find the distance between each point.
+
+As we increase $n$, the precision of which the curve is estimated increases.
+
+This means that:
+$$ len(curve) = \lim_{n \to \infty} \sum_{i=1}^{n}(\p{}$$
